CVE-2025-27796

Estado: AnalizadaCrítica (9.8)—

ReadWPGImage in WPG in GraphicsMagick before 1.3.46 mishandles palette buffer allocation, resulting in out-of-bounds access to heap memory in ReadBlob.

CVSS

Probabilidad de explotación (EPSS)

EPSS (Exploit Prediction Scoring System, de FIRST) estima la probabilidad de que una vulnerabilidad sea explotada en 30 días. Complementa a CVSS (impacto) y a CISA KEV (explotación confirmada).

🎯 Técnicas ATT&CK

Cómo se explota esta vulnerabilidad y qué consigue el atacante, en el lenguaje de MITRE ATT&CK.

Vulnerabilidad remota sin autenticación (AV:N, PR:N, UI:N) en procesamiento de archivos WPG; out-of-bounds en heap permite ejecución de código o lectura de datos. Impacto confirmado por buffer overflow (CWE-908) en ReadBlob.

Inferido por nuestro agente de análisis a partir de la descripción oficial, el vector CVSS y la CWE, y comprobado por un supervisor. Puede contener errores.
